Urethane polymer finish for pleated shades in vertical blinds

Abstract: This invention provides a urethane polymer finish for textile fabrics utilized in window coverings such as pleated shades and vertical blinds. This finish for window coverings such as pleated shades and/or vertical blinds includes a urethane polymer made from a diisocyanate and either a polyester or a polyether soft segment. The diisocyanate may be either aromatic or aliphatic with an aliphatic diisocyanate preferred to prevent yellowing. The combination of these ingredients are is either carboxylated or emulsified and then neutralized. This urethane polymer may optionally include a halogenated moiety and such as a brominated monomer. Although a one hundred percent urethane polymer finish is preferred, the actual percentage of urethane polymer in the dried finish on the textile fabric may be as low as forty-five percent and still achieve some of the significant qualities of this urethane polymer finish. Some of the these significant qualities of this urethane polymer finish include shape retention, high softening point, flame retardancy, non-blocking, stiffness, non-yellowing and light fastness.

Description: BACKGROUND OF THE INVENTION This invention relates to a urethane polymer finish for textile fabrics utilized in window coverings such as pleated shades and vertical blinds. Window coverings such as pleated shades and/or vertical blinds that are formed of textile fabric as a base material allows for considerable aesthetic variation with regard to types of fabric utilized and the coloration thereof with the advantage of having material with a firm handle that is relatively durable. The problem with typical finishes for window coverings such as pleated shades and/or vertical blinds formed of textile fabric is that pleat retention dissipates at higher temperatures. With the utilization of these pleated shades and/or vertical blinds within motorized vehicles and other similar locations that are of a relatively high temperature, pleat retention becomes a crucial consideration. Another problem with typical finishes for window coverings such as pleated shades and/or vertical blinds formed of textile fabric is that formaldehyde, triethylamine, or ammonia is utilized. All of these chemicals can pose a hazard to the environment and the inhalation of formaldehyde has been deem by OSHA to be a health risk at a specified level. Yet another problem with typical finishes for window coverings such as pleated shades formed of textile material is that hysteresis loss is high. Still another problem with some typical finishes for window coverings such as pleated shades and/or vertical blinds formed of textile fabric is that typically they do not pass the ASTM 701 Vertical Flame Test and/or the Federal Motor Vehicle Safety Standard 302 Horizontal Flame Test without the specific addition of flame retardant chemicals that can significantly alter the chemical composition of the textile finish. Another problem with typical finishes for window coverings such as pleated shades and/or vertical blinds formed of textile fabric is that resistance to discoloration is low and light fastness is poor. Yet another problem with typical finishes for window coverings such as pleated shades formed of textile fabric it that typically the finished fabric will stick to itself in a condition that is technically known as "blocking" during the formation of the pleats. Another problem of typical finishes for window coverings such as pleated shades and/or vertical blinds formed of textile fabric is that the textile finish has a low softening point. The present invention solves the above problems in a manner not disclosed in the known prior art. Summary Of The Invention This invention provides a urethane polymer finish for textile fabrics utilized in window coverings such as pleated shades and vertical blinds. This finish for window coverings such as pleated shades and/or vertical blinds includes a urethane polymer made from a diisocyanate and either a polyester or a polyether soft segment. The diisocyanate may be either aromatic or aliphatic with an aliphatic diisocyanate preferred to prevent yellowing. The combination of these ingredients is either carboxylated or emulsified and then neutralized. This urethane polymer may optionally include a halogenated moiety, such as a brominated monomer. Although a one hundred percent urethane polymer finish is preferred, the actual percentage of urethane polymer in the dried finish on the textile fabric may be as low as forty-five percent and still achieve some of the significant qualities of this urethane polymer finish. Some of the these significant qualities of this urethane polymer finish include shape retention, high softening point, flame retardancy, non-blocking, stiffness, non-yellowing and light fastness. It is an advantage of this invention to have window coverings such as pleated shades formed of textile fabric that have a high degree of pleat retention. Another advantage of this invention is that window coverings such as pleated shades and/or vertical blinds formed of textile fabric are relatively stiff. Yet another advantage of this invention is that window coverings such as pleated shades and/or vertical blinds formed of textile fabric utilizes a finish that does not include either formaldehyde, triethylamine or ammonia. Another advantage of this invention is that hysteresis loss for window coverings such as pleated shades formed of textile fabric is very low. Yet another advantage of this invention is that the textile fabric forming pleated shades and/or vertical blinds does not block unto itself. Another advantage of this invention is that the pleated shades and/or vertical blinds have very high resistance to discoloration with a high degree of light fastness. These and other advantages will be in part apparent and in part pointed out below: Brief Description Of The Drawings The above as well as other objects of the invention will become more apparent from the following detailed description of the preferred embodiment of the invention, which when taken together with the accompanying drawings, in which: FIG. 1 is a front perspective view of a pleated shade formed of textile fabric having the urethane polymer finish of the present invention; FIG. 2 is a front perspective view of vertical blinds formed of textile fabric having the urethane polymer finish of the present invention; FIG. 3 is a schematic side elevational view of the pleated shades formed of textile fabric as shown in FIG. 1 and having a chemical finish in which the pleated shades have not been subjected to heat for an extended period of time; FIG. 4 is a schematic side elevational view of the pleated shades formed of textile fabric as shown in FIG. 1 and having a chemical finish in which the pleated shades have been subjected to 76.7°C (170°F) for a period of five days; FIG. 5 is a graph of the percentage of pad concentration of polyester urethane (SANCURE® 1049A) versus stiffness for a textile fabric weighing approximately 85g (3 ounces) that is treated with a urethane polymer finish; FIG. 6 is a graph of the percentage of pad concentration of polyester urethane (SANCURE® 1049A) versus stiffness for a textile fabric weighing approximately 48.2g (1.7 ounces) that is treated with a urethane polymer finish; FIG. 7 is a graph demonstrating the softening point of a film made from the finish of present invention displaying needle penetration in millimeters versus temperature in Celsius; FIG. 8 is a graph representing pleat retention at 65.6°C (150°F) for textile fabric with a finish of the present invention versus textile fabric having a traditional vinyl chloride polymer finish; FIG. 9 is a graph representing pleat retention at 76.7°C (170°F) for textile fabric with a finish of the present invention versus textile fabric having a traditional vinyl chloride polymer finish and a traditional acrylic polymer finish with formaldehyde; Detailed Description of the Preferred Embodiment This invention relates to an improved finish for window coverings such as pleated shades and/or vertical blinds formed of textile fabric with a high degree of stiffness, no formaldehyde emission, and excellent flame retardancy. Additional properties include the ability to make a pleated structure with excellent resistance to deformation and aging at high temperatures of 65.6-76.7°C (150-170°F). The present invention includes a fabric substrate that is coated with a urethane polymer. This textile fabric can be any of a wide variety of woven or non-woven fabrics since this urethane polymer finish does not react with the textile substrate. The preferred weight range of the textile fabric is between 57.6 and 135.6g/m 2 (1.7 and 4 ounces per square yard). However, the yarns making up the textile fabric can be of virtually any denier with the only constraint being that the textile fabric cannot be either too heavy or too light to form suitable window coverings. The preferred embodiment of this urethane polymer finish is a 100% urethane polymer system, although as will be later shown and described, urethane blends are suitable. The physical properties of urethane polymers are relatively easy to obtain. The specific structural properties are proprietary, so that the only information available is whether the urethane polymer is aromatic or aliphatic, polyether or polyester, or whether carboxyl groups or cross-linking is present. The first ingredient of this urethane polymer is diisocyanate. Aliphatic diisocyanates are preferred over aromatic diisocyanates due to the possible yellowing of the textile fabric that may occur with aromatic polyurethanes. The second major ingredient is either a polyester or polyether soft segment. Although a polyester soft segment is preferred, either a polyether or polyester soft segment will suffice. Optionally, due to the presence of carboxyl groups, cross-linking can occur. A third ingredient, a halogenated moiety is deemed optional and provides flame retardant qualities for the textile finish. The preferred halogen is bromide, although chloride is a possible substitute. The preferred form of the halogenated moiety is for a monomer to be polymerized into the urethane polymer itself. Referring now to FIG. 1, a pleated shade window covering is generally indicated by numeral 10, while the individual pleats formed of textile fabric having a urethane polymer finish are represented by numeral 20. FIG. 2 is a vertical blind mechanism with an individual vertical blind slat formed of textile fabric having a urethane polymer finish and indicated by numeral 27. Both FIG. 1 and FIG. 2 demonstrate the two main types of window coverings that utilize textile fabric and can been stiffened by a chemical finish. Two typical examples of known chemical finishes for textile fabrics include polyvinyl chloride and an acrylic polymer. An example of an application of an acrylic polymer as a chemical finish for a three ounce, one hundred percent polyester fabric can be found in TABLE 1. The specific acrylic polymer is RHOPLEX® AC-604 manufactured by Rohm and Haas Company located at Independence Mall West, Philadelphia, Pennsylvania 19105. The components of this product include: an acrylic polymer, individual residual monomers, formaldehyde, triethylamine, methanol, melamine-formaldehyde resin, and water. Formaldehyde and triethylamine are deemed hazardous chemicals. Table 1 shows that in this specific example, there was 23% of this chemical in a water bath. When this chemical was then padded on 85g (three ounce), one hundred percent polyester textile fabric, the percentage of finish in relation to the total weight of the fabric and dried finish was approximately 20%. Stiffness was measured by a Handle-O-Meter that can be manufactured by Thwing-Albert Instrument Company located at 10960 Dutton Road, Philadelphia, Pennsylvania 19154. There is a ten millimeter gap in which a knife presses down on the textile fabric having the RHOPLEX® AC-604 finish. The force is measured in grams. The warp yarn bending number is typically the lower since it bends the fabric parallel to the warp yarns which is actually across the filling yarns while the higher number is the filling yarn bending number measuring the bending of textile fabric parallel to the filling yarns which is actually across the warp yarns. The stiffness across the filing yarns was 104 grams and the stiffness across the warp yarns was measured as 281 grams. Hysteresis demonstrates the ability of the textile fabric retain its original shape. Nine additional stiffness measurements are made in both the warp and filling directions with the largest difference between stiffness measurements being divided by the initial stiffness measurement in that direction. The larger the negative value indicates the decreased stability of the finished textile fabric to return to its original shape. Hysteresis is shown in Table 1 as a -22/-25. An imperative aspect of the chemical finish for window covering textile fabric is that it does not stick to itself. This is technically referred to as "blocking". The blocking test is conducted by placing finished textile fabric face to face or back to back with a five pound per square inch weight on the finished textile fabric in an oven at 180°C for one hour. During that time, the finished textile fabric should not stick to itself after cooling. With a 85g (three ounce) polyester fabric padded with twenty percent RHOPLEX® AC-604, there is typically no blockage at 176.7°C (350°F). The Federal Motor Vehicle Safety Standard 302 Horizontal Flame test fails for this acrylic polymer chemical finish as well as the ASTM 701 Vertical Flame test. Light fastness is conducted by placing textile fabric having a chemical finish under a xenon light bulb for eighty hours. The finished textile fabric is then compared to predetermined set standard specimens. Values range between zero and five with five being complete color retention and zero being absolutely no color retention. Light fastness for RHOPLEX® AC-604 applied to 85g (three ounce) polyester fabric is 4.5. Another typical known finish is a polyvinyl chloride finish. An example of this is GEON® 460X49 manufactured by B. F. Goodrich Company, Specialty Polymers and Chemicals Division that located at 911 Brecksville Road, Cleveland, Ohio 44141-3247. This is a synthetic anionic colloidal emulsion of vinyl chloride copolymer 49% (in water 51%). A specific application of GEON® 460X49 to 85g (three ounce), one hundred percent polyester fabric can be found in TABLE 2. In this Example, the percentage of chemical in the water bath is 11.5% and the percentage of finish in relationship to the total weight of the fabric and dried finish is 10.5%. Stiffness measured across the filling yarns is 50 grams, while the stiffness across the warp yarns is 147 grams. As previously stated, stiffness across the warp yarns means stiffness making a knife measurement perpendicular to the warp yarns which is actually parallel to the filling yarns and the stiffness across the filling yarns is measured by placing the knife parallel to the warp yarns. This 85g (three ounce) polyester fabric treated by GEON® 460X49 would appear to pass both the Federal Motor Vehicle Safety Standard 302 Horizontal Flame test and the ASTM 701 Vertical Flame test. Light fastness was experimentally determined to be 3.5 on the scale of five. A significant quality of this invention is the ability to retain pleat retention. Referring now to FIGS. 3 and 4, a vertical shade generally designated as numerals 30A and 30B, respectively. As shown in FIG. 3, the angle 40A between pleats is almost the same at the top of pleated shade 30A as it is near the bottom of pleated shade 30A as shown by angle 42A. As shown in FIG. 4, after being subjected to heat such as between 65.6 to 76.7°C (150 to 170°F) for a duration of three to five eight hour days, the angle between the pleated shades as designated by 40B at the upper part of the pleated shade 30B increases while the angle between the pleated shades as designated by 42B at the lower part of the pleated shade 30B decreases. This increasing angle 40B, as shown in FIG. 4, is displayed in FIG. 8 for various finishes that have been subjected for up to five days of eight hours per day in a heated environment. The line designated by the numeral 120 indicates a polyvinyl chloride finish. The line designated by the numeral 122 designates an acrylic polymer with formaldehyde finish. The line designated by numeral 124 is a urethane polymer finish of the present invention that is coating a 57.6 g/m 2 (1.7 ounces per square yard), one hundred percent polyester fabric and line indicated by numeral 126 is another urethane polymer finish of the present invention coating a 101.7 g/m 2 (3.0 ounce per square yard), one hundred percent polyester fabric. As shown in FIG. 8, the pleat retention for urethane polymer finishes is significantly better then for PVC or acrylic polymers. This presents a significant advantage for urethane polymer textile coating. FIG. 9 discloses pleat retention at 76.7°C (170°F) for duration of five days whereby each day is an eight hour day with heat and a sixteen hour cooling period where the temperature is 22.2°C (72°F). The top two lines designated by numerals 130 and 132, respectively demonstrate the application of a polyvinyl chloride finish. As shown, angle 40B as found on FIG. 4 will vary dramatically. The two lines designated by numerals 134 and 136, respectively demonstrate the application of a urethane polymer finish in which the pleat retention angle 40B as shown in FIG. 4 will not vary significantly and appears to stabilize after the third day of subjecting the textile fabric to a temperature of 76.7°C (170°F). A crucial aspect about this new innovative process is the aspect of stiffness with regard to window coverings such as pleated shades and vertical blinds. As shown in FIG. 5, any padding application beyond 14% of solids on a 101.7g/m 2 (3 ounce per square yard) polyester fabric does not enhance the stiffness to any measurable extent. As shown in FIG. 5, the line designating the stiffness taken across the filling yarns by applying a knife in a 10 millimeter slot parallel to the warp yarns is designated by numeral 112. The line designating the stiffness taken across the warp yarns by applying a knife in a 10 millimeter slot parallel to the filing yarns is designated by numeral 110. As shown in FIG. 6, a similar graph of stiffness versus percent solids in a pad bath is graphed. The line of stiffness taken across the filling yarns by bending of the warp yarns in a direction parallel thereto is designated by numeral 116. The line of stiffness taken across the warp yarns by bending of the filing yarns in a direction parallel thereto is designated by numeral 114. Once again, any additional padding of over 14% does not provide significant increase in stiffness. Another significant aspect of this urethane polymer coating is a very high softening point. The softening point is determined by needle penetration in the coated fabric. As shown by the line designated numeral 118, as shown in FIG. 7, there is very little or no penetration of the needle up to 100°C. This provides a significant advantage over vinyl chloride or acrylic polymers. It would appear that at least a 45% composition of urethane polymer in any blend is required to obtain the desired properties, while seventy-five percent provides a significant improvement in virtually significant properties and ninety percent is almost as good as one hundred percent with one hundred percent being the preferred composition of the chemical finish. Furthermore, with the 100% urethane polymer formulations, only 14% is typically needed to be added to a water bath. Some of the significant qualities of this invention include the fact that the pleating characteristics are excellent, ageing properties at room temperature and high temperature are excellent, shade hysteresis is very low, good resistance to discoloration and the light fastness of polyester fabric is excellent with usually a reading of four and above. This urethane polymer finish or blend thereof can be applied by either padding or coating. An example of a means of coating is disclosed in U.S. Patent No. 5,110,666, issued May 5, 1992, which is hereby incorporated by reference. An example of a means of padding is disclosed in U.S. Patent No. 5,240,644, issued August 31, 1993, which is hereby incorporated by reference. The invention will now be illustrated further by the following, non-limiting, Examples.
